Epsilon Eb and E Series EN Drives Reference Manual
Velocity Presets
Enter a value for each of the Velocity Presets you wish to use. The units are RPM and the
range is from ± maximum motor velocity. A positive value will cause CW motion and a
negative value will cause CCW motion. (Motor direction is determined as you face the shaft
end of the motor).
Accel/Decel Presets
Enter an Accel/Decel Presets value for each of the Velocity Presets you are using. The units
are milliseconds per 1000 RPM and the range is from 0 to 32700.0. Default is 1000 ms/kRPM.
Full Scale Velocity
This parameter is the motor velocity (in RPM) desired when the drive receives an analog
voltage equal to the Analog Input Full Scale parameter setting.
Note
Full Scale Velocity and Analog Input Full Scale do not set limits. They only set the
porportion of motor speed to Analog Input Voltage.
The Full Scale Velocity and Analog Input Full Scale parameters are used in the Analog or
Summation operating modes.
Default values:
Motor Selection
MG-205 and MG-208, NT 207, NT 212
MG-316
MG-340, MG-455, MG490 and MG-4120
Torque Mode Group
Selecting this radio button will put your drive in Torque mode and activates the Full Scale
Torque and the Torque Limit data entry boxes. In Torque mode the drive develops torque in
proportion to the voltage received on the Analog Input. The Analog Input is scaled to the
Analog Torque Command by the Full Scale Torque, Analog Input Full Scale and Analog
Input Zero Offset parameters.
For example:
5V = Motor continuous torque
10V = Motor peak torque (2 times continuous)
+10V = Peak motor torque CW
-10V = Peak motor torque CCW
